Step1.
1- Enable bluetooth on Edison1 and Edison2
"rfkill unblock bluetooth"
2- Start bluetoothctl on both devices
3- Edison1 :
power on
agent DisplayOnly
default-agent
discoverable on
4- Edison2: scan on
5- Edison2 : (also accept connection on Edison1)
trust [edison1 Mac]
pair [edison1 Mac]

Step2.
On edison 1 :
rfcomm listen 0 22

On Edison2:
rfcomm connect 0 [Edison1 Mac] 22

Failed info:
Can't connect RFCOMM socket: Connection refused

A fix for the PCI-style SST probe (used by Edison) most likely broke the ACPI-style SST probe (not used by Edison). The fix moved code from context_init (shared by both probes) directly into the PCI probe function in order to resolve a dependency. This does not affect the Edison hardware but is something that we might want to address later. The relevant commit is 3a75bd0

Hi

I'm eagerly reviewing the changes in wip-edison-3.19.5.. :) I'm currently receiving errors trying to compile the branch, but since it's a WIP I guess that's expected.

Could I trouble you to do something though? The current Intel process of having a HUGE patch file that contains all drivers and all architecture changes makes it very difficult to selectively get one piece working and integrated with a later codebase.

If you could split the commit into patches related to the base architecture changes, the power changes, the USB TO Go changes, and so forth, it'd be a lot easier to manage (and get submitted upstream).

Thanks for your consideration (and time doing the changes you are making at all!)

Oskar

1. Connect edison to Windows via ssh.
2. Flash new version.
3. Failed to connect it to windows via ssh or serial port, and disk partition folder cannot pop up.

We have tried to find some ways to solve this issue.
The first one, we input the “power on” after running the script ,but it is not successful.
The second one, after run the script,we have connected the edison to PC by manually. then run sudo pand -n --connect 00:11:22:33:55:DD --service GN can be worked successfully.

I tested with

ifconfig wlan0 up

ifconfig wlan0 down

ifconfig wlan0 up

1. Connect edison via SSH
2. Flash new version
3. Disk partition folder cannot pop up after flashing successfully.

Now I want to define one struct time by myself, and I catch the delay time between rx and ip_rcv, but I come across one problem. That's how I can replace the time into TOS when the packets are transmitting in networking. Thank you so much!

Hi

There's a missing quote at the end of this file. It leads to a warning about multi-line items being unsupported

There are two circumstances we have found where the following error periodically occurs:

One circumstance is when scanning in an environment where there are no APs present.
The other circumstance is on a Yocto Fido system with the 3.10 kernel, and with hostapd added to the system, this occurs after starting and stopping hostapd.

Hi,

I am using an Intel Edison with a MCP2515 can controller.
(my fork: https://github.com/jpilet/edison-linux/tree/edison-3.10.17-anemobox-mcp2515)

I configured the mcp251x driver to use the edison spi cs0. It works: I can "candump" the interface can0 for a while, and properly read and write from and to the bus.

However, after a few hours, the can interface stops working and dmesg tells me:

[ 5759.821413] INFO: task irq/304-mcp251x:521 blocked for more than 120 seconds.

It seems "spi_sync" never returns. The bug occurs randomly after a few hours of correct behavior. Could it be a locking problem?
Any idea?

I have seen @zhoushix's commits about SPI+DMA. However, if I enable dma for mcp151x or for spidev, the mcp151x driver can't access the controller (here https://github.com/jpilet/edison-linux/blob/9318ddd00bdc01a11f73ec6e7daeeb92aa241292/arch/x86/platform/intel-mid/device_libs/platform_mcp2515.c#L38 or here https://github.com/jpilet/edison-linux/blob/9318ddd00bdc01a11f73ec6e7daeeb92aa241292/arch/x86/platform/intel-mid/device_libs/platform_spidev.c#L29).
Am I missing something, or is it simply that the SPI+DMA code is not yet ready?

Thanks in advance for your help

if it is, maybe it should be marked as such

Hi guys,

Using the 2a02f64 from 3.19 WIP, the kernel always boots in recovery.

After a while of being in shell, the board freezes and reboots.

Hi,
Is it ok and is it safe to use wip-edison-3.19.5 branch for edison? When can we expect the official release?

Although I'm happy so lots of work is being done on a newer kernel for the Edison, I fail to understand why the choice has fallen on 3.19.5?

I thought Yocto kernels are chosen so that a preempt_rt patch exists? And this is not the case for 3.19.5. 4.0.8 would have been a more logical choice in that respect.

Or am I missing something here?
